To all whom it may concern Be it known that I, ELMoRn F. SH sTER, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Wire Straightening and Cutting-OE Machines; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in wire straightening and cutting ofi machines, and particularly to means for actuating the straightening arbor, cutting off and feed roll mechanism, whereby all of these operative elements are each properly timed 'to perform their several functions 'directly from a single source of power.

Referring to the drawings wherein i the same figures and letters of reference indicate like parts throughout the several views:

Figure 1 represents a plan view of the machine head showing a broken view of the arbor, guide bar and rock shaft; 7

Fig. 2 is a front elevation of the head and sectional view of the guide bar and rock shaft looking in the direction of arrow 0 of Fig. 1;

Fig. 3 is a side elevatiorf of the head and broken view of the guide bar and rock shaft; r

Fig. 4 is a diagrammatic view of the several gears connecting the worm shaft with one of the feed roll shafts, also cross sectional view of the cam shaft and supporting stud for the trip lever on line 44 of Fig. 1.

A brief description of such parts that are common to machines of this character comprises the head 1, rotatable arbor 2 journaled in the support 3, integral with the head, cam shaft 4, cams 5 mounted thereon, and cutting off lever 6 secured to the rock shaft 7. The lower end of this lever carries the roll8 to engage the cams 5. The

upper end of said lever carries the guide bar o I w p 1 g 9' through which the wire is fed previous fltloned train of gears, power 1s also trans to its being severed. Trip lever 10 is journaled on the bolt 11 secured to the stud 12 integral with the machine head. The horizontal part 10 of the trip lever engages the spring actuated key 13 for the purpose common to all machines of this class. The common feed rolls 14-15 are mounted on the shafts 16-.17, and these shafts are rotatably connected togetherfby the pinions 1819."

Screws 20-21 are the usual screws for controlling the feedroll'shaftsq v The new and improved features employed in connection with the several elements above enumerated, nsist of the jd-rivin pulley 22 mounted on the shaft 23 'joun' naled in standardsj24n 25, Fig, 1, is a gear mounted on the endofjthe driving shaft 23.

engaging the gear'26 journaled ,on-the stud 27. 28 1s a gear secured tothe worm shaft 29 which meshes with gear 26 and also with the gear 30 journaled on the stuol' 3l. 32

is a gear mounted'onfthe arbor 2 and isa gear'jou'rn'aled onthe stud 34 which connects the arbor gearflwitli gear 30. By'imeans of these gears, the power istransinitted di-I rectly from the driving shaft to the f's'traightening arbor. In Fig. 2, this rain of gears are also shown in their-several positions by means of dotted circles representingithe pitch line of the several gears anda'rein dicated by the same numerals. j,

7 Referring to Figs. 1, 2 and 3, 35 is a casing embracing the worm gear 36, Fig. 3, mesh ing with. the worm-37; f The casing 35 is supported on the standard 38. The w'vor 'n gear shaft 39 is journale'd in its casing 35 and the worm shaft 29 'is journaled in the shown in Figj 1. V v p I p v The worm gear shaft 39, F igs; 1, 3 and 4, carries the spur-gear 42 registering with the large gear 43 mountedon the cam shaft 4. 44is a small spur gearalso mounted on the Worm gear shaft which meshes with gear journaled on the stud '46. Gears47, 48 and 49 are journaled .on their respective studs 50,151 and 52. 'The gear 53 is joined to th'e gear 49 andmesheswith'the gear 54 mount: ed on the lower feed roll shaft 17, Fig. 2.

.The power from the .driving" pulley 22 is transmitted,as before mentioned, through standards 38 and 41. The latter standard is the train of gears 25," 26, 28,130'and 33 to the gear '32 on the straightening arbor 2.

During the rotation of the above men- 1.7, as before mentioned. In the meantime, the gear 42 is transmitting motion to the large gear 43 journaled on the cam shaft l.

When the proper length of wire has been fed through the arbor, the trip lever 10 is actuated by the wire 55 connected with well known trip mechanism on the forward part of the machine, not shown, Fig. 3, to release the key 13 and bring it under the influence of the spring 13%.Fig. 1, which spring will force the key into engagement with the large gear 13 to rotate the cam shaft l and thus actuate the cut off lever 6. As this large gear is running continuously, the key is forced back into engagement with the trip lever 10, as soon as a section of wire is severed, and by means-not showneonnected with the large gear, which means are well known and are commonly used on shafts having an intermittent rotation in connection with a normally idle running balance wheel pulley.

The varying sizes of the several gears are so arranged and constructed as to transmitto each of the moving elements, viz.: the arbor, feed rolls and cam shaft, the proper speed and timing necessary for each to antomatically and continuously perform its proper function. An electric motor could be substituted for the driving pulley shown, if so desired.

Having thus described my invention, what I claim is:

1. In a machine of the character described having a base and a head, a straightening arbor rotatably mounted thereon, feed rolls, cam shaft, and cutting off lever, of a gear mounted on the arbor, a driving shaft and its gear, a train of gears connecting the driving shaft with the arbor gear, a worm shaft and its worm, a gear of the train mounted on the worm shaft, a worm gear, a shaft therefor, means to support the worm gear shaft from the base and at right angles to the driving shaft, said worm gear meshing with the worm, spur gears mounted on the worm gear shaft, a gear mounted on one of the feed roll shafts, and a train of gears connecting one of said spur gears with the feed roll shaft gear, a gear mounted on the, cam shaft meshing with the other spur gear to actuate the cam shaft and cutting ofi lever.

3. In a machine of the type set forth, having a head, a straightening arbor and f eed rolls, a driving shaft, gearing between the armor and driving shaft to drive the former from the latter, a driven shaft connected to one of the gears of said gearing, standards supporting the driven shaft from the base of the head parallel to the driving shaft, a third shaft disposed at right angles to the driven shaft, detachable gearing supported by one of the standards to drive the third shaft from the driven shaft, and gearing between the third shaft and the feed rolls.

4. In a machine of the type set forth having a base, a straightening arbor, feed rolls, cam shaft and cutting off lever, a gear on the arbor, a driving shaft supported from the base, a train of gears between the driving shaft and said arbor gear, a worm shaft on which one of the gears of the train of gears is mounted, standards on the base supporting said worm shaft, a worm gear shaft extending at right angles to the worm shaft, gears on opposite ends of the worm gear shaft, and gears between the last named gears and the cam shaft and feed rolls respectively.

5. v In a-machine, of the type set forth, having a head, a straightening arbor, cam shaft and cutting off lever, a driving shaft, gearing between the arbor and driving shaft to drive the former from the latter, a driven shaft connected to one of the gears of said gearing, standards supporting the driven shaft from the base of the head parallel to the driving shaft, a fourth shaft disposed at right angles to the driven shaft, detachable gearing supported by one of the standards to drive the fourth shaft from the driven shaft, and gearing between the fourth shaft and the cam shaft.
